Place goat cheese in small bowl. Add pepper, lemon zest and juice. Rub baguette slices with garlic clove. Bake until just crisp, but not starting to brown, about 5 minutes. Remove from oven and immediately cut the slices in half, with a sharp serrated knife. Spread about a teaspoon of goat cheese atop the toasted baguette slices and top with crumbled bacon and a few chervil leaves. Press gently to make sure bacon and chervil are in place. Place crostini on platter and serve.
